The controllability of external thermal insulation building with vent layer was investigated numerically and empirically. At first, the heat transfer and fluid flow of a fundamental flow system were analyzed to confirm the applicability of the present numerical computation. The visualized wall temperature pattern by infrared thermography was compared with the numerical simulation, and the validity of the numerical simulation was also verified. The Optimum vent layer size, optimum thermal insulation thickness and optimum flow rate were considered along with developing the technique how to control the present thermal system by switching the vent.
